Unless you’ve been living in a cave, or under a rock, you’ve surely heard the term “Low-T” or seen an advertisement talking about how testosterone declines as men age and how the solution is undergoing testosterone replacement therapy (TRT). It promises an incredible allure: increased libido more muscle mass and strength, exploding energy levels to what they were in your youth, and a host of others. But is that the entire story Does it come with health risks Each birthday after 30 means a drop in testosterone levels by approximately 1%, and therefore 10% each decade. Do the math. By age 60 your testosterone levels will be about 30 percent lower than what they were when you were a young man. And, if you are able to live until age 80, you now have 50% of your youthful levels of the powerful masculine hormone. Congratulations! You’re now, in many ways, ½ a man. You’ve heard of menopause for women Andropause is what men experience…a natural, slow decline in testosterone levels. Sometimes, the decrease is fast, causing legitimate concerns. Symptoms of Low-T include hair loss, fatigue, low semen production, lowered sex drive, erectile dysfunction, hot flashes, infertility, loss of muscle and

Several weeks ago my column, Do you want better sex? struck a resounding note not only with female readers but also with many husbands who want their wives to have fewer headaches. The general response was, Please write more about testosterone and how it can increase female libido. Testosterone, the male hormone, has been called the hormone of desire. In males the Big T builds muscle for boys and ultimately turns boys into sexually well-functioning men. Women also produce testosterone during puberty, but only about one-tenth as much as males. Later in life they produce less, and this is why some authorities believe women lose interest in sex. How do women know if they have less testosterone and therefore less tiger in the tank? Theres a good chance testosterone is lacking if they complain of little sexual desire, lack of energy, loss of height, decreased enjoyment in life, are sad or grumpy, fall asleep after meals and produce inadequate work performance. If the answer is yes to four of these conditions, there may not be enough big T. Women may lack this hormone for several reasons. In North America 700,000 hysterectomies are done every year. The ovaries that produce estrogen

Hormone-replacement therapy significantly improved symptoms of metabolic syndrome associated with testosterone deficiency in men, a new study from Germany finds. The results will be presented Monday at The Endocrine Society’s 94th Annual Meeting in Houston. Metabolic syndrome comprises a cluster of complications that can increase the risk of heart and blood-vessel disease as well as type 2 diabetes. These complications include excess body weight, especially around the waist and torso, and abnormal concentrations of fat in the blood, known as lipids. In particular, patients with metabolic syndrome have high blood levels of the so-called bad fats, or triglycerides and low-density lipoproteins, and insufficient amounts of the healthy fats known as high-density lipoproteins. In addition, they often have high blood pressure and sugar, or glucose, levels. Previous research has linked metabolic syndrome to testosterone deficiency, which can cause decreased muscle and bone mass, depression, low energy, and decreased sex drive and ability. In addition, testosterone deficiency is also associated with the individual symptoms of metabolic syndrome, even when they are present without the other complications. “When indicated, testosterone treatment is both essential and safe in elderly patients with symptomatic late onset hypogonadism, or testosterone deficiency,” said study lead author Aksam A.

  Acidosis: The Hidden Health Destroyer Your Most Important AND Little Known Measure of Good Health What is the most important thing you should focus on for good health?Hint: it’s not your weight…or your BMI…or your cholesterol…or your triglycerides…or even your blood pressure. Without a doubt, these numbers are important. But there is one number that tells you more than these about your health, and you need to be aware of it to ward off disease and live pain-free: Your Blood pH Level The measure of acidity or alkaline in the body is potential hydrogen, or pH, which is expressed in a number between 0 and 14, and is usually measured through blood testing. A reading of 0 is pure acid, 7 is neutral, and 14 is pure alkaline. Without exception, all of your organs, bones, tissues and joints function at their best when your blood pH is slightly alkaline, which is around 7.35. Here’s a brief look at the science behind acidosis The stomach has a normal pH measure of approximately 4.0. Consuming high pH alkaline water causes the stomach pH to rise. When the stomach pH rises above 4.5, the stomach produces more hydrochloric acid. Here is the

A study testing the effect of testosterone has found that it dramatically lowers cooperation between individuals, making people more egocentric. In this study, people performed their task more poorly under the influence of testosterone. It didn’t affect their individual performance, but the lack of cooperation it caused resulted in partners making the wrong choice more frequently than they did when not under the influence of testosterone. Oh, and by the way, all the subjects were women. Self-centered, unwilling to listen, and overly sure of yourself. This is your life on testosterone, even if you are female. The study was of 17 pairs of women who had never met before. Each pair participated in two sessions held three to seven days apart. In one session, both women were given an oral testosterone supplement (80 mg of testosterone undecanoate) six to seven hours before the session. For the other session, neither woman received testosterone. Each session consisted of 192 trials. In each trial, the women sat at separate computer screens and were shown the same two sets of images. Each set contained six images of a grating. In one set, one image was sharper (higher contrast) than all the others. The women

Testosterone can skew one’s judgment, creating the impression that decisions are best taken alone even in situations that call for collaboration, according to a study released Wednesday. In a clever set of experiments, scientists led by Nicholas Wright at the University of London showed that women given a dose of testosterone become less inclined to act in concert even when it was clearly in their interest to do so. Finding the right balance between working together and going solo-and knowing when to do one or the other-is an essential life skill. In some circumstances, joining forces with others is the best way to achieve a desired result: that’s why lions and hyenas hunt in packs, and why humans cooperate on the playing field, in the laboratory, or in battle. Sometimes, however, decisive individual action is needed to break free of group-think, or to come out ahead of the game. To a significant extent, our ability to navigate between these two extremes is acquired through learning and experience, but some of these impulses are hardwired too. Earlier research, for example, on the biological underpinnings of group decision making revealed that a naturally-occurring hormone, oxytocin, promotes the urge to work side-by-side. At

DICK AHLSTROM, Science Editor IT CAN happen in juries and local groups, in Dáil committees and company board rooms. Too much testosterone can thwart good decision-making. People have long blamed the male hormone for damaging group dynamic and now University College London researchers have proven this to be true.   Toss in some excess testosterone and co-operation tends to go out the window. Dr Mark Wright and colleagues at the Wellcome Trust Centre for Neuroimaging at UCL tested the impact of testosterone on the levels of co-operative decision-making accomplished by groups. They publish their findings this morning in the journal Proceedings of the Royal Society B . Other experiments had already shown that subjects given the female hormone oxytocin tended to be more co-operative. The university team wanted to see whether testosterone could produce the opposite effect, Dr Wright said. Men already have high levels of the hormone and if extra is given it will quickly be broken down. For this reason only women were used as subjects, Dr Wright said. Supplements were given to elevate their testosterone levels temporarily and the women conducted a series of tests to measure levels of co-operation. Dr Wright used 17 pairs of female volunteers

  Washboard abs and a chiseled jaw are a draw, but a recent study suggests it may be a man’s healthy immune system that really turns women on. That makes sense, since a strong immune system signifies a healthy guy – one who’s likely to survive long enough to pass his rugged genes to the next generation. But the more surprising thing is that women can apparently spot good immunity by looking at a guy’s face. The key factor may be testosterone, the male hormone that has been associated with a man’s hardy good looks. According to a study published in the journal Nature Communications, testosterone levels are not only linked with facial attractiveness, but also with a strong immune system response. MORE: Why Fathers Have Lower Levels of Testosterone To figure out the complex relationship between hormones and hotness, researchers from Abertay University in the U.K. studied 74 Latvian men in their early 20s. They gave the men a Hepatitis B vaccine, which triggers the immune system to produce antibodies to fight the virus, and took blood samples before and after. Using the blood samples, researchers measured the men’s antibody levels, as well as levels of testosterone and the
